LED BULB

摘要

PURPOSE: An LED bulb is provided to simultaneously emit the light emitted in an LED to surroundings by increasing the reflective angle of ambient light but also direct illumination. CONSTITUTION: A glass case(100) opens a lower part and forms a constant space inside. A half mirror coating layer is formed and has a constant light transmission rate and a constant light reflection rate in an inner circumference. A substrate(200) is arranged in the glass case. A plurality of LEDs is arranged in the lower part of the substrate. A cover(400) is combined with the bottom of the glass case and transmits LED radiation.
